1. simplify -7x-3x+2 to -10x+2 -10x+2=-8x-8 2. add 10x to both sides 2=-8x-8+10x 3. simplify -8x-8+10x to 2x-8 2=2x-8 4. add 8 to both sides 2+8=2x 5. simplify 2+8 to 10 10=2x 6. divide both sides by 2 10/2=x 7. simplify 10/2 to 5 5=x 8. switch sides x=5
1. simplify x-4x to -3x -8-x=-3x 2. add x to both sides -8=-3x+x 3. simplify -3x+x to -2x -8=-2x 4. divide both sides by -2 -8/-2=x 5. two negatives make a positive 8/2=x 6. simplify 8/2 to 4 4=x 7. switch sides x=4 hope this helps
