Answer:
1. -2, 2. -23, 3. 25
Step-by-step explanation:
1. -2+5x8/-12= step 1: add -2+5
-2+5=3 step 2: 3(8)
3x8= 24 step 3: 24/-12
24/-12= -2
2. -2(9-4)+3=? step 1: combine like terms -2(9) and -2(-4)
-18-8+3=? step 2: combine like terms
-26+3=? step 3: combine like terms
-23=?
3. 2x + 130=180 step 1: -130 on both sides
2x = 50 step 2: /2 on both sides
x = 25

Substitue 2x for y in the second equation:
