X = 3
Combine like terms: -4 + -5 = -9
-9 + 6x + -3x = 0
Combine like terms: 6x + -3x = 3x
-9 + 3x =0
Solving -9 + 3x = 0
Solving for variable ‘x’
Moving all terms containing my x to the left, all other terms to the right
Add ‘9’ to each side of the equation -9 + 9 + 3x = 0 + 9
Combine like terms: -9 + 9 = 0
0+3x=0+9
3x = 0 + 9
Combine like terms: 0 + 9 = 9
3x = 9
Divide each side by ‘3’.
X = 3

Answer:
x = -1
, y = 5
Step-by-step explanation:
Solve the following system:
{5 x + 3 y = 10 | (equation 1)
x = y - 6 | (equation 2)
Express the system in standard form:
{5 x + 3 y = 10 | (equation 1)
x - y = -6 | (equation 2)
Subtract 1/5 × (equation 1) from equation 2:
{5 x + 3 y = 10 | (equation 1)
0 x - (8 y)/5 = -8 | (equation 2)
Multiply equation 2 by -5/8:
{5 x + 3 y = 10 | (equation 1)
0 x+y = 5 | (equation 2)
Subtract 3 × (equation 2) from equation 1:
{5 x+0 y = -5 | (equation 1)
0 x+y = 5 | (equation 2)
Divide equation 1 by 5:
{x+0 y = -1 | (equation 1)
0 x+y = 5 | (equation 2)
Collect results:
Answer: {x = -1
, y = 5
Answer:
8¹
Step-by-step explanation:
The given expression is :
8 to the power 1.
We need to write it in exponential form.
If we write 10³, here 10 is base and 3 is exponent.
8 to the power 1 = 8¹
The base is 8 and exponent is 1.
Hence, the exponential form is 8¹.
