Simplify the expression: 2(3x – 5) + 4x - 7

Ksivusya [100]

Answer:

$\huge{ \fbox{ \sf{10x - 17}}}$

Step-by-step explanation:

$\sf{ \: 2(3x - 5) + 4x - 7}$

Distribute 2 through the parentheses

$\mapsto{ \sf{6x - 10 + 4x - 7}}$

Add the like terms : 6x and 4x

Like terms are those which have the same base.

$\mapsto{ \sf{10x - 10 - 7}}$

$\underline{ \text{Remember!}} :$ The negative integers are always but added but posses the negative ( - ) sign.

$\mapsto{ \sf{10x - 17}}$

Hope I helped!

Best regards! :D

Help please!! i’ll reward branliest, 50 points

Nina [5.8K]

Answer:

Madeline: y=1x+9

Issac: y=2x+1

x=8, y=17

Step-by-step explanation:

Solving for X:

Multiply Issac's by -1:

y= 1x+ 9

-y=-2x-1

Combine:

0=-x+8

Add x to both sides:

x=8

Solving for Y:

Since we already have x, we only need to input the x value into one of the formulas:

y=1(8)+9

Simplify parenthesis with multiplication:

y=8+9

Add:

y=17

If you feel unsure, check your work with both equations:

(17)=2(8)+1

17=16+1

17=17=Good

(17)=1(8)+9

17=8+9

17=17=Good

Please give a brainliest and a thx ;)

I hope this helps u :)
