Two health clubs offer different pricing plans for their members. Both health clubs charge a one-time sign-up fee and a monthly membership fee. The equation y=42x+45y=42x+45 represents what Health Club B charges. Health Club A charges a $35 sign-up fee and $51 per month.

Complete the solution of the equation. find the value of y when x equals to 6 4x+y=20

Solve the following simultaneous equation by using an algebraic method (either substitution or elimination) 2x + 3y=-4 4x-y=11
