Put the equation in standard form with a positive x coefficient. 2y+5=-4(x+2)

umka21 [38]

The standard form of equation is: 4x+2y = -13

Step-by-step explanation:

the standard form of a linear equation in two variables is given by:

$ax+by = c$

Given equation is:

$2y+5=-4(x+2)$

Distributing -4 into the round bracket

$2y+5 = -4x-8$

Adding 4x on both sides

$4x+2y+5 = -4x-8+4x\\4x+2y+5 = -8$

subtracting 5 from both sides

$4x+2y+5-5 = -8-5\\4x+2y = -13$

The standard form of equation is: 4x+2y = -13

What is T in -5t-2(5t+10)=100

Alina [70]

Answer:

t=-8

Step-by-step explanation:

-5t-2(5t+10t)=100

-2 x 5t=-10t

-2 x 10 = -20

-5t-10t-20=100

combine terms and add 20

-15t=120

divide by -15

t=-8
