Question

5(7x-8)-2(52+8)=5(3z+5)-1​

Answer 1

Answer:

after opening tge bracket, we get

(5×7x)-(5×8)-(2×52)+(-2×8)=(5×3z)+(5×5)-1

35x-15z=24+40+104

35x-15z=168

Answer 2

Answer:

35 * -40 -3 * 60 = 15z + 25 -1

• -1400 - 120 = 15z + 24
• -1520 = 15z + 24
• 15z = 24 + 1520
• 15z = 1544
• z = 1544/15
