It is an equation and the value of x works out as 88

If x equals 10 and y equals 10, then 9x plus 8y equals 170.

y = 5

15x+7y = 4 5x+7y = 2 Subtract the bottom equation from the top equation to eliminate y which will leave you with: 10x = 2 Divide both sides by 10 to find the value of x: x = 2/10 = 1/5 in its lowest terms. Substitute the value of x into the original equations to find the value of y: Therefore: x = 1/5 and y = 1/7

y = 5x + 3When x=2,y = 5(2) + 3 = 10 + 3 = 13

10+100+10 is 120 so A=120.

x+16=26Subtract 16 from both sides and you will find that is equal to 10, x=10 and that's its value.

That depends on the value you give to 'm'.
