SimplifyingY + -9 = 4(x + -2) Reorder the terms:-9 + Y = 4(x + -2) Reorder the terms:-9 + Y = 4(-2 + x)-9 + Y = (-2 * 4 + x * 4)-9 + Y = (-8 + 4x) Solving-9 + Y = -8 + 4x Solving for variable 'Y'. Move all terms containing Y to the left, all other terms to the right. Add '9' to each side of the equation.-9 + 9 + Y = -8 + 9 + 4x Combine like terms: -9 + 9 = 00 + Y = -8 + 9 + 4xY = -8 + 9 + 4x Combine like terms: -8 + 9 = 1Y = 1 + 4x SimplifyingY = 1 + 4x
Well first we know that 55.50 is 25% so I guess multiply it by 3 to get the full price equalling nearly 166 which is closest to 165, so that’d be my answer. Sorry if wrong.
