1. Rewrite the expression. Use an exponent, rather than repeated multiplication. (–4)(–4)

AlekseyPX

-4^2 is the same as -4*-4

-4*-4=16

-4^2= 16

-4^2 is the exponent.

3x+10y=13<br> 4(-2y+x)-9x=13

mart [117]

Answer:

$x=-9$

$y=4$

Step-by-step explanation:

$3x+10y=13$ ← Equation 1

$4(-2y+x)-9x=13\\$

By simplifying the above equation we get,

$-8y+=4x-9x=13$ (Simplifying the brackets)

$-8y-5x=13$ (By subtracting $-9x$ from $+4x$ ) ← Equation 2

Multiply Equation 1 by 5 and Equation 2 by 3 and add them together.

Equation 1 multiplied by 5 will give,

$15x+50y=65$

Equation 2 multiplied by 3 will give,

$-24y-15x=39$

Add those together,

$15x+50y-24y-15x=65+39$

$26y=104$ (After simplifying $x$ values)

Therefor $y=4$

By substituting $y=4$ to Equation 1 we get,

$3x+10*4=13$ $3x+40=13\\3x=-27\\x=-9$

Therefor we can say,

$x=-9$

$y=4$
