Sorry if i'm wrong
Step-by-step explanation:
Answer:
5x=45, 7x+3=66, and 7x+8=71
Step-by-step explanation:
5x+7x+3+7x+8=182
Rearrange
5x+7x+7x+8+3=182
Add everything up
19x+11=182
Subtract 11 from both sides
19x=171
Divide both sides by 19
x=9
Plug x=9 into all spaces with x
5*9=45 , 7*9+3=66 , and 7*9+8=71
Voila!

Let's use the addition/subtraction method.
Suppose we wish to eliminate variable x.
Mult the first eqn by 5: 10x - 15y = 15
Mult the 2nd eqn by -2: -10x+ 4y = -8
Add these two equations together: -11y = 7, and y = -7/11.
Subst. -7/11 for y in either given equation and find x.
Then your solution is (x,y) (subst. the values we've found for x and y).
