Ns algebraically. (6 pts)

olve the following system of equations algebra

2x + 3y + 4z = 3

3x - 4y + 2z = - 13

x + 5y - 3z = 22

Use properties to find the sum or product 21+25+39+5

What are the interpretations of the line 3x - 15y = 60? X-intercept y-interception A: x 20 - y - 4 B: x 5 - y 20 C: x - 3 - y 15 D: x - 4 - y 20

Write the equation in standard form using integers: y = - 2/5x - 3

Which expression is equivalent to the given expression? 8 (3/4a) - 8 A. 3/4 a B. 6a C. 8 (3/4a-1) D. 3/4a-1
