Answer:
1
Step-by-step explanation:
when a variable does not have an exponent the degree is always one. Ex: 8x is the same as 8x to the power of 1
Set it up as 15x-13+8x+29+2y=180 and then just find a algebra calculator and put that formula in there
7x+2y=24
<span>-8x-2y=-30 (multiplied each side by -1)
-x = -6
x = 6
</span>7x+2y=24
7(6)+2y=24
42+2y=24
2y = -18
y = -9
