It's a linear equation in ' a '.

When you see one of these, it often happens that curiosity overtakes you, and you begin to wonder about the numerical value of ' a ' that makes the equation true. Let's find out:

3a - 7a + 12 = 32

3a - 7a = 20

-4a = 20

a = 20 / (-4) = -5

The equation is true if ( a = -5 ).

first add 12 plus 12 equals 24, then add 4 plus 4 and that equals 8. 24 plus 8 equals 32. 12 + 12 = 24 4 +4 =8 24 + 8 =32

x=12

y=84-72=12 z=84-52=32 x=84-12-32=40

You plug in the values of x and y and solve 12x + 16y = ? 12(1) + 16(2) = 12 + 32 = 44
