Add 4x - 2 to each side: 5x = 5 x = 1
2x + 7 = 1 Therefore, 2x = -6 x = -6/2 x = -3
3
(x + 7)2 = 5 x + 7 = ±√5 x + 7 - 7 = -7 ± √5 x = -7 ± √5
6x-7=8x+9 bring the x over -7=2x+9 take the 9 over -16=2x divide both sides by 2 x=-8

Can you help with this equation? Thanks. Solve for x and y and z for the following. x plus y plus z equals 9 x plus 2y plus 3z equals 23 x plus 5y plus -3z equals -7
x=-2
-3+x=7. x=10
8+-1= 7 x=-1
x=7
x= -8
How do you solve 4y plus x equals 8
Solve for x. 3x + 3 = x + 7 2x + 3 = 7 2x = 4 x = 2 Check it. 6 + 3 = 2 + 7 It checks.
you do 3 plus 5 first then you get 8 you have to find out what minus 7 equals 8
p is obviously zero because any number x plus 0 equals itself.
Assuming the question is "solve for x", the answer is x=5
