If x = 2y + 3 and 3x = 7 – 4y, what does x equal?

Step-by-step explanation:

x=2y+3

3x=7-4y

Rearrange the numbers so they compare,

x=2y+3

3x=-4y+7

Multiply the first equation by 2 (this is so the variable with y matches in both equations)

2x=4y+6

3x=-4y+7

Add the two equations together

2x=4y+6

+

3x=-4y+7

5x=13

Divide both sides by 5 to isolate x

x=13/5

Simply the equation

x=2 3/5

the 1st digit is in the 100s n its 1

step-by-step explanation:

3,589÷18 = 199.389

so the first digit of the quotient is in the 100s n its 1

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
