I think it’s 1.4 but I’m not 100% sure
Answer:
The answer is ( - 8, 8) in point form or in x = -8 , y= 8 in equation form.
Answer:
x = 2
, y = -7
Step-by-step explanation:
Solve the following system:
{y = 1 - 4 x | (equation 1)
{y = -2 x - 3 | (equation 2)
Express the system in standard form:
{4 x + y = 1 | (equation 1)
{2 x + y = -3 | (equation 2)
Subtract 1/2 × (equation 1) from equation 2:
{4 x + y = 1 | (equation 1)
{0 x+y/2 = -7/2 | (equation 2)
Multiply equation 2 by 2:
{4 x + y = 1 | (equation 1)
{0 x+y = -7 | (equation 2)
Subtract equation 2 from equation 1:
{4 x+0 y = 8 | (equation 1)
{0 x+y = -7 | (equation 2)
Divide equation 1 by 4:
{x+0 y = 2 | (equation 1)
{0 x+y = -7 | (equation 2)
Collect results:
Answer: {x = 2
, y = -7
Answer:
x=2
Step-by-step explanation:
3(x-4) = 2(-2x+1) [Distribute]
-> 3x - 12 = -4x + 2 [Simplify]
-> 7x = 14 [Divide by 7 on both sides]
-> x = 2
