Solve by substitution: y=3x+14 y=-4x

x = -2 and y-8

Step-by-step explanation:

First, you substitute the y into the first equation.

-4x = 3x + 14  Subtract by 3x on both sides so you can isolate the variable

-7x = 14 Divide by -7 on each side

x = -2

Then, substitute x into the equation

y = -4x

y = -4 (-2)

y = 8

answer:   rlly

step-by-step explanation:

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
