Chapter 4: Q37. (page 158)

Solve each system of equations.

3x-3y=6-6y=-305z-2x=6

Short Answer

Expert verified

The solution of given system of equation is 7,5,4.

Step by step solution

01

– Description of step.

Divide each side of -6y=-30 by -6.

鈭�6y鈭�6=鈭�30鈭�6y=5
02

– Description of step.

Substitute 5 for y into 3x-3y=6 and simplify to obtain the value of x.

3x鈭�35=63x鈭�15=63x3=213x=7
03

– Description of step.

Substitute 7 for x into 5z-2x=6 and simplify to obtain the value of z.

5z鈭�27=65z鈭�14=65z5=205z=4

Therefore, the solution of given system of equation is 7,5,4.
