Give the equations of two different lines that are perpendicular to the line 3x + 4y = 7.

Given abcd ac=38 and ae=3x+4 find the value of x

Sundar used linear combination to solve the system of equations shown. he did so by multiplying the first equation by 5 and the second equation by another number to eliminate the y-terms. what number did sundar multiply the second equation by? 2x+9y=41 3x+5y=36
