Let's solve your equation step-by-step.
2(x+4)=−5x+1
Step 1: Simplify both sides of the equation.
2(x+4)=−5x+1
(2)(x)+(2)(4)=−5x+1(Distribute)
2x+8=−5x+1
Step 2: Add 5x to both sides.
2x+8+5x=−5x+1+5x
7x+8=1
Step 3: Subtract 8 from both sides.
7x+8−8=1−8
7x=−7
Step 4: Divide both sides by 7.
7x
7

x=−1
Answer:
x=−1
7a + 6c + 9a - 15c
-- Look for all the 'a's 7a, 9a
-- Addum up 16a
-- Look for all the 'c's 6c, -15c
-- Addum up -9c
-- Write the results 16a - 9c
Base from the given that <span>tan X =sin X / cos X. so the answer to the question what is tan ( 90 - A) is:
first let X = 90 - A
substituting from the given that
</span>tan X =sin X / cos X
tan ( 90 - A) = sin ( 90 - A) / cos ( 90 - A)
