220

Step-by-step explanation: You just do inverse operation 55x4=220, check 220/4=55.

x=220

Step-by-step explanation:

x /4 =55

Step 1: Multiply both sides by 4.

x/ 4  =55 ( x 4 )*(4)=(55)*(4)

x=220

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
