Step-by-step explanation:
-3x + 10 = 34
Subtract 10 from both sides:
-3x = 24
Divide both sides by -3:
X = 24 / -3
X = -8

I have two questions to solve
-3x+10=34
13x-4=11x+10-8
Combine like terms on the right side:
13x -4 = 11x + 2
Subtract 11x from both sides:
2x -4 = 2
Add 4 to both sides:
2x = 6
Divide both sides by 2:
X = 6/2
X = 3
Step-by-step explanation:
3(x-7) + 4 = 22
or,3x-21+4 = 22
or, 3x-17 = 22
or, 3x = 22+17
or, x = 39/3
x = 13
In slope intercept form they are...
-x+3y=2 is y=1/3x+2/3
x+y=-2 is y=-x-2
