Find the solution to the following: *

Trava [24]

Answer:

First one: x = all real numbers

Second one: x = 0

Step-by-step explanation:

for the first one

given 8x+10=2(4x+5) we need to isolate the variable (x) using inverse operations

step 1 distribute the 2 to what is in the parenthesis ( 4x and 5 )

2 * 4x = 8x

5 * 2 = 10

now we have 8x + 10 = 8x + 10

step 2 subtract 8x from each side

8x - 8x = 0

now we have 10 = 10

subtract 10 from each side

10 - 10 = 0

we're left with 0 = 0 meaning that all real numbers are solutions

For the second one

given 3x-8=2(x-4) once again we need to isolate the variable using inverse operations

step 1 distribute the 2 to what is in the parenthesis (x - 4)

2 *x = 2x

2 * -4 = -8

now we have 3x - 8 = 2x - 8

step 2 add 8 to each side

-8 + 8 = 0

now we have 2x = 3x

step 3 subtract 2x from each side

3x - 2x = x

2x - 2x = 0

we're left with x = 0

2x + 3y = 26 3x + 5y = 40 find x and y I will give brainliest

Yuki888 [10]

Answer:

x = 10 and y = 2

Step-by-step explanation:

multiply first equation by 5 and 2nd equation by 3 then subtract equation 1 and 2, we get,

10x+15y= 130

9x+15y=120

( -) (-) (-)

x= 10

substituting the value of x in equation 1 we get

2x + 3y = 26

2*10 + 3y = 26

3y = 26-20

y =6/3

y= 2.i hope this helps
