What is the solution to this equation? 4x+10+3x=40-3x

x = 3

Step-by-step explanation:

Step 1: combine like terms

On the left side, you can combine 4x and 3x to get 7x and the right side is already simplified

Now we have 7x+10=40-3x

Step 2: subtract 10 from both sides

10-10 = 0 and 40-10 = 30

Now we have 7x = 30-3x

Step 3: Add 3x to both sides

7x +3x = 10x and 30-3x+3x = 30

Now we have 10x =30

Step 4: divide by 10 on both sides

10x/10 = x and 30/10= 3

Therefore, we have x =3

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.

it is true
