Q. What value of z makes the equation below true?10z+5=757101115
Subtract 5 from both sides: We need to solve the equation for z. Start by subtracting 5 from both sides of the equation to isolate the term with z.10z+5−5=75−5
Isolate term with z: After subtracting 5 from both sides, we get: 10z=70
Divide by 10: Now, divide both sides of the equation by 10 to solve for z.1010z=1070
Find value of z: After dividing by 10, we find the value of z:z=7
