Question

1)make x the subject of h=4(x+3y)+2 2) make a the subject of a^2+b^2=c^2

Answer 1

`(h-12-2)/(4) = x` & a² = c² - b²

Explanation:

h = 4 (x + 3y) + 2

Expand brackets

h = 4x + 12y + 2

Subtract 12y & 2 from both sides

h - 12y - 2 = 4x

Divide both sides by 4

`(h-12-2)/(4) = x`

a² = c² - b²

Then √ both sides to lose the ²
