On the right is a circle with centre (0, 0), radius r and (x, y) any point on the circle. Distance between (0,0) and (x, y) equals the radius, r. If the centre is (0, 0), the equation of the circle will be of the form x2 + y2 = r2.

Please solve, -7x+8=-4(x+1)

omeli [17]

Answer: $x=4$

Simplify both sides of the equation.

$-7x+8=-4(x+1)\\-7x+8=(-4)(x)+(-4)(1)(Distribute)\\-7x+8=-4x+-4$

Add 4x to both sides

$-7x+8+4x=-4x-4+4x\\-3x+8=-4$

Subtract 8 from both sides

$-3x+8-8=-4-8\\-3x=-12$

Divide both sides by -3

$-3x/-3=-12/-3\\x=4$
