you have to solve the ones in the brackets first. so in this instance, 4(-1) = -4.\n\nand then, you solve -4 - 3 = -7

t-(4/t)=3\ncan be rewritten as\nt^2 - 3t - 4 = 0\n\nthis has 2 possible solutions:\nt=-1\nor\nt=4

for the equation 4m-5=3m=7 cannot be solved therefore i will infer that it is plus, since the equal bar can be shifted to it.\n\n\n4m-5=3m+7\n\nyou take away the m, since it is on both sides, so now it will read\n\n4-5=3+7\n\nwhich is -1=10, and since that does not work, it is -1 does not equal (a /  is over = to show this) 10\n\nnow i have reread the guidelines and now see i can do another problem, and here it is\n\n\n\n4m+2=10\nalso, since you are practically working backwards to do the equation, you need to the order of operations backwards (now it is add and subtract first, multiply and divide second, exponents third, etc)\n\nyou must do the opposite of what is given, for example, when see it is adding two, you subtract two, when you see it is multiplying by 2, divide by 2\n \nwhatever you do to one side, you must do on the other side\n\nso \n4m+2-2=10-2\n \n4m=8\n\nnow since m and 4 are multiplying, you need to divide the 4 to make the m alone\n 4m divided by 4=8divided by 4\n\nm=2\n\n\nnow to check your work,  4 times 2+2=10 (4 times 2 is eight, and add by two is 10)

Focus on -(x+1).\nIt's like multiplying every term inside the bracket by -1. Hence you're going to get -x-1.\n4 - x - 1 = 8\n3 - x = 8\nAdd x to both sides: 3 = 8+x\nSubtract 8 from both sides: -5 = x\n\nHope this helps :)
