(y-30)/5=x

4x + 2(3x) = 30 10x = 30 x= 3. Y= 9. (3,9)

y = 28 + ¾x y = 30 + ½x → 28 + ¾x = 30 + ½x → ¾x - ½x = 30 - 28 → ¼x = 2 → x = 2 × 4 = 8 → y = 30 + ½ × 8 = 30 + 4 = 34 → solution is the point (8, 34) (ie x = 8, y = 34)

x = 14

x + y + x = 2x + y

x = y = 0 ?

x-int. is -5 y-int. is 6

(1, 9)

30 - 12 = 18

Can you help with this equation? Thanks. Solve for x and y and z for the following. x plus y plus z equals 9 x plus 2y plus 3z equals 23 x plus 5y plus -3z equals -7

y equals x plus 5 is the equation of a straight line in the x-y plane.
