Simplifying
34 = 10 + 4q
Solving
34 = 10 + 4q
Solving for variable 'q'.
Move all terms containing q to the left, all other terms to the right.
Add '-4q' to each side of the equation.
34 + -4q = 10 + 4q + -4q
Combine like terms: 4q + -4q = 0
34 + -4q = 10 + 0
34 + -4q = 10
Add '-34' to each side of the equation.
34 + -34 + -4q = 10 + -34
Combine like terms: 34 + -34 = 0
0 + -4q = 10 + -34
-4q = 10 + -34
Combine like terms: 10 + -34 = -24
-4q = -24
Divide each side by '-4'.
q = 6
Simplifying
q = 6

Answer:
Multiply by 3 -> 3(x - y = 6)
Step-by-step explanation:
Cuz since the 2nd is positive 3y
u need a negative 3y to get rid of it
3(x - y = 6)
2x + 3y = 7
3x - 3y = 18
2x + 3y = 7
5x/5 = 25/5
x = 5
5 - y = 6
-5 -5
-y/-1= 1/-1
y = -1
