Answer:
Number 4 is: x=2
Number 5 is: x= 8
Number 6 y= -2
Step-by-step explanation:
Number 4: Divide both sides by -5 then simplify 25/5 to 5 then add 7 to both sides then simplify -5+7 to 2
Number 5: simplify 2x+3+5x to 7x+3 then subtract 3 from both sides then simplify 59-3 to 56 then divide both sides by 7 and simplify 56/7 to 8
Number 6: simplify 3y+9-5y to -2y+9 then subtract 9 from both sides , then simplify 13-9 to 4 then divide both sides by -2 then simplify -4/2 to -2 :)
