You can only add or subtract like terms. So, you subtract 9x from 2x, which gives you -7x. Then subtract -9 from 3 to get -6. And you are left with -7x -6.

2x + 3 = x + 1 Subtract x from both sides: x + 3 = 1 Subtract 3 from both sides: x = -2
4x plus 2 equals 2x plus 5?
4x + 2 = 2x + 5 Subtract through by 2x 2x + 2 = 5 Subtract through by 2 2x = 3 Divide through by 2 x = 1.5 ■
Multiply this number by 4 and subtract 39 to get twice the number plus 3?
4x-39 = 2x+3, 4x-2x = 42 x=21
In the expression 2x plus 3 equals 9. What is the value of x?
You first must use SADMEP or PEMDAS backwards. (parentheses, exponent, multiply and divide, add and subtract) With this information you must ether add or subtract first 2x + 3 = 9 (Now, subtract 3 from each side of the equation) 2x + 3 - 3 = 9 - 3 (and the result is...)2x = 6 (whatever you do to one side of the equation you must do to the other.) 2x = 6 (Divide both sides by 2)2x/2 = 6/2 (and you get...) x = 3
